Four and a half billion years ago, the young Earth was a hellish place—a seething chaos of meteorite impacts, volcanoes belching noxious gases, and lightning flashing through a thin, torrid atmosphere. Then, in a process that has puzzled scientists for decades, life emerged. But how? (49:53)

Solids, liquids, and gases are the substance of every substance in the physical world. With the quest for low temperatures came the discovery that, under the right conditions of temperature and pressure, all elements can exist in each of the basic states of matter.

Asteroids are celestial bodies that orbit around the sun. The word asteroid means star-like and is derived from the Greek words – astor (star) and oid (shape). They are believed to be remnants of the humungous cloud of dust and gases that formed the sun and planets over 4 billion years ago. (01:59)

This video shows the mass of Jupiter, how long it takes to complete a rotation, what makes up the clouds, and what makes up the bands of color on the planet. It discusses the Red Spon on the planet, what gases make up Jupiter, the gravity on the planet, how many moons Jupiter has, and the rings Jupiter has. It also discusses what the rings are made up of. The video consists of awesome pictures. This video is set to music, the words are on the pages, there is no voice narration. (08:08)

This is a look at the facts of Saturn. These facts include the density and what it is compared to, what gases make it up, how hot it is, the length of the day, the rings around the planet and what makes up the rings, the tilt of the planet, and things that take place on the land of the planet. Awesome pictures in this video. This video is set to music; there is no narration. (07:31)

Lesson ObjectiveStudents duplicate a "magic trick" and explain the science behind it. Questions to ConsiderWhy does Mr. Haigh first demonstrate but not explain the lab?Notice how the lab requires students to apply their knowledge of science to a novel taskWhat do students learn about pressure and density as it applies to liquids and gases?

Gases are everywhere, and this is good news and bad news for chemists. The good news: when they are behaving themselves, it's extremely easy to describe their behavior theoretically, experimentally and mathematically. The bad news is they almost never behave themselves.
In this episode of Crash Course Chemistry, Hank tells how the work of some amazing thinkers combined to produce the Ideal Gas Law, how none of those people were Robert Boyle, and how the ideal gas equation allows you to find out pressure, volume, temperature or number of moles. You'll also get a quick introduction to a few jargon-y phrases to help you sound like you know what you're talking about. (09:03)

We've all seen pictures of Earth from space, but have we really taken the time to appreciate what our planet looks like against the starscapes of the Milky Way galaxy? Here, we beckon viewers to see Earth in its cosmic context, which includs the stars, interstellar gases, the moon, the sun, and the solar winds. (04:15)

The fossil record reveals much about the diversity and development of species. This program examines the traces left by early plants, animals, and single-celled organisms and follows the progression of life forms over time. Connections are drawn between atmospheric gases, climate change, rock formation, biological functions, and mass extinctions.

What evidence is there that the Earth's climate is changing? This FRONTLINE/NOVA: 'What's Up with the Weather?' investigates the Earth's climatic history, using polar ice core data. Gases and particles trapped in each layer of ice reveal a highly variable global climate, plus instances of radioactive fallout and massive volcanic eruptions.

In this video Paul Andersen describes the four major spheres on planet Earth. The geosphere makes up the mass of the planet and includes the major landforms. The hydrosphere is all of the water and the atmosphere is all of the gases. The biosphere exists where the others spheres interface. (06:09)

The Kyoto Protocol is a treaty signed in 1997 under the United Nations Framework Convention on Climate Change (UNFCCC). Its goal is to mitigate the negative impacts of greenhouse gas emissions on the environment and global climate. The treaty requires developed countries to reduce their emissions of greenhouse gases, such as carbon dioxide, to below their 1990 levels. (03:46)
